RELATED APPLICATION

This application is a continuation-in-part of my copending application U.S. Ser. No. 337,932, filed Jan. 7, 1982, now abandoned.

BACKGROUND OF THE INVENTION

This invention relates to ortho-heterocyclic sulfonylureas and in particular, to their use as agricultural chemicals such as herbicides and growth regulants.

U.S. Pat. No. 4,127,405 teaches compounds which are useful for controlling weeds in wheat having the formula: ##STR1## R₃ and R₆ are independently hydrogen, fluorine, chlorine, bromine, iodine, alkyl of 1-4 carbon atoms, alkoxy of 1-4 carbon atoms, nitro, trifluoromethyl, cyano, CH₃ S(O)_(n) - or CH₃ CH₂ S(O)_(n) -;

R₄ is hydrogen, fluorine, chlorine, bromine or methyl;

R₅ is hydrogen, fluorine, chlorine, bromine, methyl or methoxy;

R₇ is hydrogen, fluorine, chlorine, bromine, alkyl of 1-2 carbon atoms or alkoxy of 1-2 carbon atom;

R₈ is hydrogen, methyl, chlorine or bromine;

R₉ and R₁₀ are independently hydrogen, methyl, chlorine, or bromine;

W and Q are independently oxygen or sulfur;

n is 0, 1 or 2;

X is hydrogen, chlorine, bromine, methyl, ethyl, alkoxy of 1-3 carbon atoms, trifluoromethyl, CH₃ S- or CH₃ OCH₂ -; and

Y is methyl or methoxy; or their agriculturally suitable salts; provided that:

(a) when R₅ is other than hydrogen, at least one of R₃, R₄, R₆ and R₇ is other than hydrogen and at least two of R₃, R₄, R₆ and R₇ must be hydrogen;

(b) when R₅ is hydrogen and all of R₃, R₄, R₆ and R₇ are other than hydrogen, then all of R₃, R₄, R₆ and R₇ must be either chlorine or methyl; and

(c) when R₃ and R₇ are both hydrogen, at least one of R₄, R₅ or R₆ must be hydrogen.

French Pat. No. 1,468,747 discloses the following para-substituted phenylsulfonamides, useful as antidiabetic agents: ##STR2## wherein R=H, halogen, CF₃ or alkyl.

Logemann et al., Chem. Ab., 53, 18052g (1959), disclose a number of sulfonamides, including uracil derivatives and those having the formula: ##STR3## wherein R is butyl, phenyl or ##STR4## and R₁ is hydrogen or methyl.

When tested for hypoglycemic effect in rats (oral doses of 25 mg/100 g), the compounds in which R is butyl and phenyl were most potent. The others were of low potency or inactive.

Wojciechowski, J. Acta. Polon. Pharm. 19, p. 121-5 (1962) [Chem. Ab., 59 1633 e] describes the synthesis of N-[(2,6-dimethoxypyrimidin-4-yl)aminocarbonyl]-4-methylbenzenesulfonamide: ##STR5## Based upon similarity to a known compound, the author predicted hypoglycemic activity for the foregoing compound.

Netherlands Pat. No. 121,788, published Sept. 15, 1966, teaches the preparation of compounds of Formula (i), and their use as general or selective herbicides, ##STR6## wherein R₁ and R₂ may independently be alkyl of 1-4 carbon atoms; and

R₃ and R₄ may independently be hydrogen, chlorine or alkyl of 1-4 carbon atoms.

Compounds of Formula (ii), and their use as antidiabetic agents, are reported in J. Drug. Res. 6, 123 (1974), ##STR7## wherein R is pyridyl.

European patent application No. 7687, discloses herbicidal sulfonylureas which contain an o-carboalkoxybenzene moiety.

The presence of undesired vegetation causes substantial damage to useful crops, especially agricultural products that satisfy man's basic food needs, such as soybeans, barley, wheat, and the like. The current population explosion and concomitant world food shortage demand improvements in the efficiency of producing these crops. Prevention or minimizing the loss of a portion of valuable crops by killing, or inhibiting the growth of undesired vegetation is one way of improving this efficiency.

A wide variety of materials useful for killing, or inhibiting (controlling) the growth of undesired vegetation is available; such materials are commonly referred to as herbicides. The need exists, however, for still more effective herbicides that destroy or retard weeds without causing significant damage to useful crops.

Alkylation of this product with a C₁ -C₄ alkyl iodide using procedures known to those skilled in the art leads to products in which R₅ is H, CH₃ or CH₃ CH₂ and R is C₁ -C₄ alkyl.

Also produced in the alkylation are compounds in which R is C₁ -C₄ alkyl and R₈ is H, CH₃ or CH₃ CH₂ and R₉ is H, CH₃ or CH₃ CH₂ as shown in Equation 33-B. ##STR87##

R. H. Wiley and L. L. Bennett, Jr., Chem. Rev., 44, 447-476 (1944).

Compounds of Formula (10y) in which Q is ##STR89## are best prepared by displacement of halogen from the corresponding halo aromatic nitro compound with the imidazole salt as shown in Equation 34. ##STR90## The reaction is conducted in the presence of an appropriate solvent such as dimethylformamide, N-methylpyrrolidone or THF at temperatures from ambient to reflux and for a period of one to twenty-four hours. The procedure is especially useful when R₁₄ is H, CH₃ or CH₃ CH₂. When R₁₄ is CH₃ S, CH₃ O or CH₃ CH₂ O in (10y), these substituents are best introduced by displacement of the corresponding iodo, bromo or chloro derivatives of 10y.

The following examples serve to more fully illustrate the preparation of compounds of this invention. All temperatures are in degrees centigrade and all parts are by weight unless otherwise indicated.

EXAMPLE 1 Preparation of 2-(2-oxazolyl)benzenamine

To 19.0 g of 2-(2-nitrophenyl)oxazole, (prepared by the procedure of W. E. Cass, J. Am. Chem. Soc., 64, 785 [1942]) 3.0 g of Raney-Nickel catalyst (purchased from Aldrich Chemical Company, Milwaukee, Wisc. 53201) and 200 ml ethanol were combined and reduced at ambient temperature and at a H₂ pressure of 5-50 psi on a Paar Hydrogenator until the hydrogen uptake ceased. The catalyst was filtered through celite under a blanket of nitrogen. The solvent was removed on a rotary evaporator. 17.4 g of crude product with m.p. 31°-32° was obtained and used in the next step.

EXAMPLE 2 Preparation of 2-(2-oxazolyl)benzenesulfonamide Diazotization

To 100 ml H₂ O and 180 ml of concentrated HCl was added 40.0 g of 2(2-oxazolyl)benzenamine. The mixture was cooled to 0°-5°. To this mixture was added dropwise a solution of 18.6 g NaNO₂ in 30 ml of water, keeping the temperature in the range of 0°-5° during the addition. The reaction mixture was stirred for 15 minutes after the nitrate addition was complete.

Coupling (Sulfonyl Chloride Formation)

A second flask was charged with 100 ml glacial acetic acid, 100 ml concentrated HCl and 4.3 g CuCl₂. The mixture was cooled to 0°-10° C.

The diazonium salt was added dropwise to the coupling mixture during a period of 15 minutes while maintaining the temperature between 0°-10° C. The progress of the reaction was monitored by nitrogen evolution via. a bubbler attached to the reaction vessel. When nitrogen evolution ceased (approximately 2 hours reaction time), the reaction mixture was poured into 1500 ml ice-water. The crude solid sulfonyl chloride was filtered and converted directly to the sulfonamide in the next step. A small dried sample had a m.p. of 88°-89° C.

Amination (Sulfonamide Formation)

The crude solid product from the previous step was added to a solution of 400 ml tetrahydrofuran containing excess aqueous ammonia and cooled to 10°-15°. The reaction mixture was stirred for 30 minutes. 300-400 ml of water was added to the reaction mixture, which was then extracted several times with CH₂ Cl₂. The CH₂ Cl₂ extracts were combined and back extracted with water, then dried with anhydrous MgSO₄. The solution of the product was filtered and the solvent removed on a rotary evaporator yielding 36.4 g of crude sulfonamide with m.p. 139°-140°.

EXAMPLE 3 Preparation of N-[(4-methoxy-6-methylpyrimidin-2-yl)aminocarbonyl]-2-(oxazol-2-yl)benzenesulfonamide

Under N₂, 5.5 ml of 2 M(CH₃)₃ Al in toluene (purchased from Aldrich Chemical Co., Milwaukee, Wisc.) was added to 2.2 g (0.01 m) of 2-(2-oxazolyl)benzenesulfonamide dissolved in 80 ml dry CH₂ Cl₂. The reaction was stirred for 15 minutes after the addition. 2.1 g of solid 4-methoxy-6-methylpyrimidin-2-yl)carbamic acid, methyl ester, (prepared by procedures described previously) was added. The reaction was stirred at ambient temperature for one hour and then refluxed for approximately 16 hours. After cooling to 10° C., 50 ml of water was added cautiously, dropwise, followed by enough glacial HOAc to lower the pH of the reaction mixture to 3.0. The crude reaction mixture was extracted several times with CH₂ Cl₂. The extracts were dried with anhydrous Na₂ SO₄, filtered, and the solvent stripped on a rotary evaporator. The crude product was triturated with n-butyl chloride-ethyl acetate 1:1. The resulting solid was filtered yielding 1.6 g product with m.p. 208-209°(d).

EXAMPLE 4 Preparation of 1-Methyl-2-(2-nitrophenyl)-1H-imidazole

Under N₂, 9.5 g of 2-(2-nitrophenyl)-1H-imidazole in a solution of 100 ml dimethylformamide and 25 ml of anhydrous tetrahydrofuran cooled to 0°-5° C., was treated with 2.3 g of a 50% mineral oil dispersion of NaH. After the N₂ evolution ceased, 8.5 g of CH₃ I was added dropwise over a period of 15 minutes maintaining the temperature at 0°-5°. The reaction mixture was allowed to warm to ambient temperature and then stirred for two hours. The reaction mixture was then poured into water. The aqueous suspension of the product was extracted several times with CH₂ Cl₂. The extracts were combined and dried with anhydrous Na₂ SO₄. The solvent was removed on a rotary evaporator. The last traces of dimethylformamide were removed under high vacuum; a waxy solid remained. The crude product was crystallized from CH₃ CN. Two crops totaling 3.6 g were obtained. The m.p. was 89°-90°.

EXAMPLE 5 Preparation of 2-(1-methyl-1H-imidazol-2-yl)benzenamine

28.0 g Nitro compound from the preceding step was added to 120 ml of concentrated HCl and cooled to 0°-10° C. A solution of 96.6 g of SnCl₂ ·2H₂ O in 120 ml concentrated HCl (cooled to 0°-10° C.) was added to the nitro compound. The reaction mixture was warmed to 50° on a steam bath to complete the reduction.

The reaction mixture was poured into ice-water and the pH raised to 10-12 with 50% NaOH solution. The precipitated product was filtered and taken up in CH₂ Cl₂.

EXAMPLE 6 Preparation of 2-(1-methyl-1H-imidazol-2-yl)benzenesulfonamide Diazotization

16.0 g of Amino compound from the preceding step was added to 100 ml of concentrated HCl and cooled to 0°-5°. A solution of 6.7 g NaNO₂ in 15 ml of water was added dropwise maintaining the temperature at 0°-5°. The reaction mixture was stirred 10 minutes after the addition was completed.

Coupling

Into a vessel cooled to 0°-5° C. were charged 50.0 ml HCl, 0.16 g CuCl₂ and 21.5 ml SO₂. The cooled diazonium salt from the preceding step was added dropwise over a period of 10-15 minutes keeping the temperature between 0°-5° C. The reaction was stirred for 1 hour at 0°-5° C. A yellow precipitate formed which was filtered. A small sample of this product was crystallized from CH₃ CN and had a m.p. of 215°-218° C. The spectral data and color are more consistent with the tricyclic salt ##STR91## (1H-imidazo[1,2-β][1,2]benzisothiazol-1-ium, 1-methyl-5,5-dioxide chloride) rather than the sulfonyl chloride ##STR92## The salt was then aminated as described below.

Amination

The crude yellow solid from the preceding step was dissolved in water and enough concentrated aqueous NH₃ was added to raise the pH to 9.0. The reaction mixture was stirred at ambient temperature for about 30 minutes. The reaction mixture was poured into H₂ O and then extracted with CH₂ Cl₂, dried with anhydrous Na₂ SO₄ and the solvent removed on a rotary evaporator. 4.5 g of crude product was obtained. The product was purified by dry column chromatography on silica gel with 1% EtOH/EtOAc. The purified product was washed from the silica with MeOH. The MeOH was removed on a rotary evaporator yielding 3.6 g of product sulfonamide with a m.p. 158°-163°.

Under N₂, 2.3 ml of a 2 M solution of (CH₃)₃ Al was added dropwise to a solution of 1.0 g of sulfonamide from the preceding step in 40 ml of CH₂ Cl₂. The mixture was stirred at ambient temperature for 15 minutes after which 0.89 g of (4,6-dimethoxypyrimidin-2-yl)carbamic acid, methyl ester was then added. The reaction was stirred at ambient temperatures for 15 minutes and then heated to reflux for 16 hours.

The reaction mixture was cooled to 10° and 50 ml of water was added dropwise. The crude reaction mixture was extracted with CH₂ Cl₂ several times. The organic extract of the product was dried with anhydrous Na₂ SO₄, filtered and the solvent removed on a rotary evaporator. The crude product was triturated with EtOAc and filtered. 0.5 g of product with m.p. 182°-183° was obtained.

EXAMPLE 8 Preparation of 2-(4,5-dihydro-4,4-dimethyloxazole-2-yl)benzenesulfinic acid, lithium salt

To 200 ml of dry tetrahydrofuran was added 16.3 g (0.1 M) of 2-phenyl-4,4-dimethyl-4,5-dihydrooxazole (prepared by the procedure taught in J. Org. Chem., 28, 2759 [1963]). The solution was cooled to -30° to -40° and 65 ml of 1.6 M solution (0.105 M) of butyl lithium was added dropwise while maintaining the temperature. After the addition the reaction was allowed to warm to 0°. The reaction was stirred for one hour at 0° and then cooled to -40°. While maintaining the temperature, 4.7 ml of sulfur dioxide was added dropwise. When the last drop of SO₂ was added, the reddish yellow solution of the lithium agent turned lemon yellow. The reaction was stirred for one hour after the addition and allowed to warm to room temperature. The solvent was stripped on a rotary evaporator leaving a solid residue which was triturated with anhydrous ether. The product was filtered and dried in a vacuum oven at 70° for 16 hours.

EXAMPLE 9 Preparation of 2-(4,5-dihydro-4,4-dimethyloxazol-2-yl)benzenesulfonamide

21.0 g of sulfinic acid from the preceding step was dissolved in 150 ml of anhydrous tetrahydrofuran and cooled to -50°. To this mixture was added a solution containing approximately an equivalent amount of chloramine prepared as follows: (see Coleman and Hauser, J. Am. Chem. Soc., 50, 1193 (1928). To 12.0 gms of aqueous NH₃ and 300 ml of ether cooled to 0°-5° C. was added 286 g of aqueous NaOCl (5.25%) also cooled to 0°-5° C. The mixture was stirred for 15 minutes. The ether layer was separated, the aqueous phase was extracted with 100 ml of ether cooled to 0°. The ether extracts were cooled to -30° and dried with anhydrous CaCl₂. The resulting cold ethereal chloramine solution was added to the sulfinic acid maintaining the temperature at -30° to -50°. The reaction mixture was allowed to warm to 0° to -10° C. and stirred for 30 minutes. The reaction mixture was then allowed to warm to ambient temperature over a period of one hour. The reaction mixture was extracted once with an aqueous NaHSO₃ solution and then dried and filtered. The ether was stripped on a rotary evaporator to yield an oil. Trituration with CH₂ Cl₂ yielded 1.1 g of product with m.p. 142°-146°. Dry column chromatography of the filtrate on silica gel with ethyl acetate yielded an additional 1.2 g of product with m.p. 138°-142°.

EXAMPLE 10 2-(4,5-dihydro-4,4-dimethyloxazol-2-yl)-N-[(4,6-dichloro-1,3,5-triazin-2-yl)aminocarbonyl]benzenesulfonamide

To 1.1 g of sulfonamide from the preceding step dissolved in 15 ml of anhydrous tetrahydrofuran under N₂ at ambient temperature was added a solution of 0.78 g of 4,6-dichloro-1,3,5-triazine isocyanate dissolved in 5 ml of anhydrous tetrahydrofuran. The reaction mixture was refluxed for 30 minutes. After cooling to ambient temperature, the solvent was removed on a rotary evaporator. The crude product was triturated with hexane and filtered yielding 1.7 g which was used in the following step without further purification.

A solution of 16.0 g of 5-[(2-phenylmethylthio)phenyl]oxazole in a mixture of 100 ml of acetic acid and 10 ml of water was cooled to 5° and 9.1 ml of chloride was added portionwise while maintaining the temperature below 15°. When addition of chlorine was complete, the yellow-brown solution was stirred 15 minutes at 5°-10° then poured into 600 ml of ice water. The aqueous mixture was extracted with ether. The organic solution was washed with water (3×250 ml) followed by brine (50 ml), then dried over anhydrous magnesium sulfate, filtered and the solvent removed under reduced pressure. The crude reaction product was dissolved in 150 ml of tetrahydrofuran and cooled to 0°-5°. Ammonium hydroxide (8.0 ml) was added dropwise. The red-orange suspension was stirred 20 minutes at 0°-5° then allowed to warm to ambient temperature and stirred until TLC (Hexane/ethyl acetate-1:1) showed no sulfenyl chloride remained. The solvent was removed under reduced pressure and the resulting oily solid triturated with 250 ml of cold water. The resulting oily solid was collected and washed sequentially with water, butyl chloride/hexane (1:1), isopropyl alcohol and butyl chloride giving 7.1 g of the title compound as a slightly yellow solid, m.p. 157°-163°; ir (mull) 3420 and 3210 cm⁻¹ (NH₂).

Formulations

Useful formulations of the compounds of Formula I can be prepared in conventional ways. They include dusts, granules, pellets, solutions, suspensions, emulsions, wettable powders, emulsifiable concentrates and the like. Many of these may be applied directly. Sprayable formulations can be extended in suitable media and used at spray volumes of from a few liters to several hundred liters per hectare. High strength compositions are primarily used as intermediates for further formulation. The formulations, broadly, contain about 0.1% to 99% by weight of active ingredient(s) and at least one of (a) about 0.1% to 20% surfactant(s) and (b) about 1% to 99.9% solid or liquid diluent(s). More specifically, they will contain these ingredients in the following approximate proportions:

Lower or higher levels of active ingredient can, of course, be present depending on the intended use and the physical properties of the compound. Higher ratios of surfactant to active ingredient are sometimes desirable, and are achieved by incorporation into the formulation or by tank mixing.

Typical solid diluents are described in Watkins, et al., "Handbook of Insecticide Dust Diluents and Carriers", 2nd Ed., Dorland Books, Caldwell, New Jersey, but other solids, either mined or manufactured, may be used. The more absorptive diluents are preferred for wettable powders and the denser ones for dusts. Typical liquid diluents and solvents are described in Marsden, "Solvents Guide," 2nd Ed., Interscience, New York, 1950. Solubility under 0.1% is preferred for suspension concentrates; solution concentrates are preferably stable against phase separation at 0° C. "McCutcheon's Detergents and Emulsifiers Annual", MC Publishing Corp., Ridgewood, New Jersey, as well as Sisely and Wood, "Encyclopedia of Surface Active Agents", Chemical Publishing Co., Inc., New York, 1964, list surfactants and recommended uses. All formulations can contain minor amounts of additives to reduce foaming, caking, corrosion, microbiological growth, etc.

The methods of making such compositions are well known. Solutions are prepared by simply mixing the ingredients. Fine solid compositions are made by blending and, usually, grinding as in a hammer or fluid energy mill. Suspensions are prepared by wet milling (see, for example, Littler, U.S. Pat. No. 3,060,084). Granules and pellets may be made by spraying the active material upon preformed granular carriers or by agglomeration techniques. See J. E. Browning, "Agglomeration", Chemical Engineering, Dec. 4, 1967, pp. 147ff. and "Perry's Chemical Engineer's Handbook", 5th Ed., McGraw-Hill, New York, 1973, pp. 8-57ff.

The ingredients are blended and milled to pass through a 100 mesh screen. This material is then added to a fluid bed granulator, the air flow is adjusted to gently fluidize the material, and a fine spray of water is sprayed onto the fluidized material. The fluidization and spraying are continued until granules of the desired size range are made. The spraying is stopped, but fluidization is continued, optionally with heat, until the water content is reduced to the desired level, generally less than 1%.

Utility

The compounds of the present invention are powerful herbicides. They have utility for broadspectrum pre- and/or post-emergence weed control in areas where complete control of all vegetation is desired, such as around fuel storage tanks, ammunition depots, industrial storage areas, parking lots, drive-in theaters, around billboards, highway and railroad structures. Alternatively, some of the subject compounds are useful for selective pre- and/or post-emergence weed control in crops, such as wheat and barley.

The rates of application for the compounds of the invention are determined by a number of factors, including their use as selective or general herbicides, the crop species involved, the types of weeds to be controlled, weather and climate, formulations selected, mode of application, amount of foliage present, etc. In general terms, the subject compounds should be applied at levels of around 0.01 to 10 kg/ha, the lower rates being suggested for use on lighter soils and/or those having a low organic matter content, for selective weed control or for situations where only short-term persistence is required.

The compounds of the invention may be used in combination with any other commercial herbicide examples of which are those of the triazine, triazole, uracil, urea, amide, diphenylether, carbamate and bipyridylium types.

The herbicidal properties of the subject compounds were discovered in a number of greenhouse tests. The test procedures and results follow: ##STR141##

Test A

Seeds of crabgrass (Digitaria sp.), barnyardgrass (Echinochloa crusgalli), wild oats (Avena fatua), cassia (Cassia tora), morningglory (Ipomoea sp.), cocklebur (Xanthium sp.), sorghum, corn, soybean, rice, wheat and nutsedge tubers (Cyperus rotundus) were planted in a growth medium and treated pre-emergence with the chemicals dissolved in a non-phytotoxic solvent solution of the compounds of Table A. At the same time, cotton having five leaves (including cotyledonary ones), bush beans with the third trifoliolate leaf expanding, crabgrass, barnyardgrass and wild oats with two leaves, cassia with three leaves (including cotyledonary ones), morningglory and cocklebur with four leaves (including the cotyledonary ones), sorghum and corn with four leaves, soybean with two cotyledonary leaves, rice with three leaves, wheat with one leaf, and nutsedge with three to five leaves were sprayed with a non-phytotoxic solvent solution of the compounds of Table A. Other containers of the above mentioned weeds and crops were treated pre- and post-emergence with the same non-phytotoxic solvent so as to provide a solvent control. A set of untreated control plants was also included for comparison. Pre-emergence and post-emergence treated plants and controls were maintained in a greenhouse for sixteen days, then all treated plants were compared with their respective controls and rated visually for response to treatment.

The following rating system was used:

0=no effect;

10=maximum effect;

C=chlorosis and/or necrosis;

D=defoliation;

E=emergence inhibition;

G=growth retardation;

H=formative effects;

U=unusual pigmentation;

X=axillary stimulation; and

6Y=abscised buds or flowers.

The data indicate that the compounds tested are highly active herbicides. Certain of the compounds have utility for selective weed control in wheat.

Test B

Two plastic bulb pans were filled with either Fallsington silt loam or Woodstown sandy loam soil. One pan was planted with corn, sorghum, Kentucky bluegrass and several grass weeds. The other pan was planted with cotton, soybeans, purple nutsedge (Cyperus rotundus), and several broadleaf weeds. The following grass and broadleaf weeds were planted: crabgrass (Digitaria sanguinalis), barnyardgrass (Echinochloa crusgalli), wild oats (Avena fatua), johnsongrass (Sorghum halepense), dallisgrass (Paspalum dilatatum), giant foxtail (Setaria faberii), cheatgrass (Bromus secalinus), mustard (Brassica arvensis), cocklebur (Xanthium pensylvanicum), pigweed (Amaranthus retroflexus), morningglory (Ipomoea hederacea), cassia (Cassia tora), teaweed (Sida spinosa), velvetleaf (Abutilon theophrasti), and jimsonweed (Datura stramonium). A 12.5 cm diameter plastic pot was also filled with prepared soil and planted with rice and wheat. Another 12.5 cm pot was planted with sugarbeets. The above four containers were treated pre-emergence with several test compounds within the scope of the invention.

Twenty-eight days after treatment, the plants were evaluated and visually rated for response to the chemical treatments utilizing the rating system described previously for Test A. The data are summarized in Table B.

Test C

Two ten-inch in diameter plastic pans lined with polyethylene liners were filled with prepared Fallsington silt loam soil. One pan was planted with seeds of wheat (Triticum aestivum), barley (Hordeum vulgare), wild oats (Avena fatua), downy brome (Bromus tectorum), cheatgrass (Bromus secalinus), blackgrass (Alopecurus myosuroides), annual bluegrass (Poa annua), green foxtail (Setaria viridis), quackgrass (Agropyron repens), Italian ryegrass (Lolium multiflorum) and ripgut brome (Bromus rigidus). The other pan was planted with seeds of Russian thistle (Salsola kali), tansy mustard (Descuraina pinnata), Galium aparine, tumble mustard (Sisymbrium altissium) kochia (Kochia scoparia), shepherd's purse (Capsella bursa-pastoris), Matricaria inodora, black nightshade (Solanum nigrum), yellow rocket (Barbarea vulgaris), wild mustard (Brassica kaber) and wild buckwheat (Polygonum convolvulus). The above two pans were treated pre-emergence. At the same time two pans in which the above plant species were growing were treated post-emergence. Plant height at the time of treatment ranged from 1-15 cm depending on plant species.

The compounds applied were diluted with a non-phytotoxic solvent and sprayed over-the-top of the pans. An untreated control and a solvent alone control were included for comparison. All treatments were maintained in the greenhouse for 20 days at which time the treatments were compared to the controls and the effects visually rated. The recorded data are presented in Table C. It will be noted that the compounds tested have utility for selective pre- and post-emergence weed control in wheat and barley.

Test D

The test chemicals, dissolved in a non-phytotoxic solvent, were applied in an overall spray to the foliage and surrounding soil of selected plant species. One day after treatment, plants were observed for rapid burn injury. Approximately fourteen days after treatment, all species were visually compared to untreated controls and rated for response to treatment. The rating system was as described previously for Test A. The data are presented in Table D.

All plant species were seeded in Woodstown sandy loam soil and grown in a greenhouse. The following species were grown in soil contained in plastic pots (25 cm diameter by 13 cm deep): soybeans, cotton, alfalfa, corn, rice, wheat, sorghum, velvetleaf (Abutilon theophrasti), sesbania (Sesbania exaltata), sicklepod (Cassia obtusifolia), morningglory (Ipomoea hederacea), jimsonweed (Datura stramonium), cocklebur (Xanthium pensylvanicum), crabgrass (Digitaria sp.), nutsedge (Cyperus rotundus), barnyardgrass (Echinochloa crusgalli), giant foxtail (Setaria faberii) and wild oats (Avena fatua). The following species were grown in soil in a paper cup (12 cm diameter by 13 cm deep): sunflower, sugar beets, and rape. All plants were sprayed approximately 14 days after planting. Additional plant species such as bindweed and johnsongrass are sometimes added to this test.

It will be seen that the compounds tested are highly active post-emergence herbicides. Wheat is relatively tolerant.
